=Wl1i0hx the following is a specification, refer-' ence being had to the accompanying drawings.

-My inventionrelates to stereotyping apparatus, and has for its object to provide means for autometicelly'supplying type-metal to the casting-box.

A further object is to provide forsupplying the .typemetal in measured quantities or charges each suflicient to make a east, end also tohutom'atmally connect the castin charge. B

box with a source of so ply of the molten metal when the casting ex is moved into position to receive the charge. I accomplish these objects in the manner hereinafter described and as illustrated in the drawings.

What I regard as new is set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved apparatus, showing the casting-box in position to receive a charge. Fig; 2 isntplan view thereof. Fig 3 is a side elevation showin the position of the casting-box before or after it receives a ig. 4 is ,a detail, bein e partial sectional view of the casing of t e castingbox. Fig. 5 is a cross-section of the castingbox. Fig. 6 is a sectional View of the apparatus shown in Figs. 1, 2, and 3. :Fig. 7 1s an enlarged detail of a part of the ledling mechanisin. Fi 8 is asection on line 8 8 of Fig. 7 Fig. 9 IS a detail of the operating-lever;

and Fig. 10 is an elevation, partly in section,

of parts thereof.

Referring tothe drawings, 1 indicates a. furnace in which the type-metsl is reduced to a molten condition, said furnace having a bowl '12 in the upper portion thereo'f which is preferably hemispherical in form, as shown in ig. 6. It will be understood that the furnace is provided with means under the bowl for supplying the requisite heat.

13 indicates a measuring-ladle comprising a bowl 14 and a stem 15. The bowl 14 is er ranged at an angle to the stem and is em ployed to dip up the molten 'type-metel. It

is of such cepacit r as to hold just the proper specification of Lettere Patent. Application filed February 21, 1903. Serial lie. 144,59=

amount of type-metal requisite to charge the casting-box. funnel-shaped, its larger end being nearer the bowl M. The ladle is pivotslly mounted at one edge of the bowl 12 upon a shaft 16 by The stem 15 is tubular and means of lugs 17, which project from the uuder surface of the stem 15 near its end, as shown in Fig. 6. By this construction by rocking the indie 13 on the shaft 16' it may be dipped into the bowl 12 to take up a charge or may be turned up to a niore or less hori-- zontel oosition to discharge the contents of its bowl is through the tubular-stem.

18 indicates a spout, one end of which is pivotally connected with the shaft l6 by lugs 19 and. telescopes u on the adjacent end of the stem 15, being iared, as shown at 20 in Figs. 6 and .7, for this PUIJOSG and to guard against accidental escape oi type-metal. The oppositeend of the spout i8 is adapted to dischar e into the casting-hex, as will he hereinafter explained.

21 indicates the casting-box, which may be of any approved t e, single or multiple. in the construction il lhstrated i have shown an ordinary single casting-box mounted upon trunnions 22, provided with bearings inn frame 23. The casting-box 21 consists of the usual case 24 and core 25, pivoted to the case by a pivot 26, so that it may be swung into or out of operative position for the insertion of matrices and thc removal of stereotyped plates. As will be understood by those fin miliar with the art, in the form of casting-- hox illustrated the matrix is placed in position when the casting-box is in its horizontal position and the core is in the elevated position. (Illustrated 'in dotted lines in Fig. 3.) The core 25 is then turned down into the case, occupying the position shown in Fi 3 illustratedin section in Fig. 5. hen the parts are properly locked together, the casting-hox is turned upon its trunnions to asubstantielly vertical position, as shown in Fig. 6, and a charge of molten typo-metal is poured in at the upper end, thereby forming the stereo'ty ed plate. The casting-box is then and ICO

turned own egain to its horizontal position and the piste removed.

In my improved a paratus the castingbox is so mounted in t e frame 23 that when turned to its upri ht position the spout 18 will project over t is upper end of the core in the manner shown in Fig. 6, so as to discharge the contents of the ladle 13 between the core and the case. The re uisite cooperation of the ladle and castingox is secured by means of cranks 27 28, mounted, respectlvely, on the shaft 16 and one of the trunup, another charge, and when the casting-box is in its upright position the ladle is. carried into position to discharge. In order to fa.- cilitate the turning of the casting-box to its upright position, a counterbalance 30 is provide connected by a flexible connection- 31 to the castiug-box 24, which passes over apulley 32, supported by the furnace 11, as

shown in Fig. 3. The counterbalauceiw not only assists. in raising the cast' box, but also, throu h the connection of said castingbox with t e shaft 16,, assists in raising the ladle with its charge into discharging position.

33 indicates a stop. which intercepts the lower end of the casting-box 24, as shown in Fig. 6, and prevents it from moving beyond the proper point when turned to its upright position.

Obviously it is important that the ladle should not discharge its contents into the spout '18 until the castin -box is in position to receive its charge, an to insure such op.- eration provision is made by which the final tipping up of the ladle, by which the molten ty e-nletal is discharged from it, is eflected suddenly after the spout 18has ahead as sumed an inclined position and is rea y to direct the type-metal to the castingox This is accomplished in the followi I manner: The crank 27, on which the sha t 16 is rocked, is mounted loosel upon said shaft and is connected therewit through a collar 34:, which is keyed upon said shaft or secured thereto by a set-screw 35, as shown in Fig. 10. The collar 34 is provided with a recess 36, adapted to receive a lug 37, projecting laterally from the hub 38 of the crank 27, as shown in Fig. 10. The recess 36 is considerably wider than the lug 37., so that the crank '27 may swing through an arccof preferably fifteen or twenty degrees independently of the shaft 16, the object being to permit the shaft 16 to rotate to that extent after the crank 27 reaches its lowermost position. One of the lugs 19, by which the spout 18 is pivoted up'onthe shaft 16, is connected by a sleeve 39 with the hub 38 of the crank 27, as

best shown in 10, and the other lug 19 of said spout is loosel mounted on the shaft 16, as best shown in ig. 10. By this construction the spout 18 is rigidly connected with the crank 27 and moves therewith. The lugs 17, by which the ladle 13 is connected with the shaft 16, are keyed'to said shaft, preferably by set-screws40, so that the ladle l3 rocks with said shaft and has no movement independently thereof. 41 indicates a lever by which the shaft 16 is rocked to a limited extent inde endently of the crank 27. Said lever 41 has ahub or boss 4 2,by-which it is connected to the shaft 16 a set-screw 43 or I other equivalent device serving to secure said boss to the shatt. By the construction described when the casting-box is lifted from the position shown in Fig, 3 the crank 28. acting through connecting: rod 29, draws down crank 27, therebygrocking spout 18 down'to meet the casting box. At first the shaft 16 is not rotated; but a'sfsoon. as'thelu 3.7 reaches the upper end of the recess 36 ans engages the collar 34 the shafit 16. be to rock, carrying with it the ladle 13, w 'ch is carried up out of the bowl 1 2, swinging about the shaft 16 as a pivot. When the casti box reaches its upright osition, (shown, in Fig. 6,) the spout 18 will have reached-the sition shown inthe same figure, but the adle 13 will not as yet have been tilted sum ciently to discharge its' contents i-nt'o said. s out. At this time the lug 3'2 will: still bat-m t e upper end of the recess 315,. be' held: in such p sition by the weight of the la 10. The 0 erator then presses down on the lever .41., t ereby rockingshaft 16 independently of the crank 27 and of the spout 18 to tilt the ladle sufficiently to discharge its contents into the u .per end of said spout. When the cast has been made, the tru'uing down 'of the casting-box to its horizontal position returns the ladle and spout to the positions shown in Fi 3, this being accomplished; alu tomatically y the action of the cranks 27 28 and coimecting-rod 29 1 7 1 wish it to be understood that while I have described my improvements in detail, as illustrated inthe 'accompan ing drawi my invention is not restricts tothe speci 19 details of the construction described, but in cludcs as well the invention enericalty set I forth in the broader claims. 1 oreover, my improvements are not restricted in their aprplication to apparatus for casting stereotype. pates.
